Changing your WiFi password or replacing your router can cause your TV remote app to stop finding your TV because the connection between your phone and TV is no longer valid. The good news is that this problem is usually easy to fix without resetting your TV or buying a new remote.
Many people assume the TV or remote app is broken after changing their home network. In reality, smart TVs remember the previous network settings, while mobile remote apps depend on both devices being connected to the same local network. Once that connection changes, the app can no longer discover the TV.
This guide explains why it happens, how to reconnect your TV, and what to do if your TV still does not appear. You will also learn how to use Universal TV Remote Control to reconnect quickly and control your TV again.
Why Does a TV Remote App Stop Finding Your TV After Changing WiFi?
A TV remote app stops finding your TV because your phone and TV are no longer communicating on the same local network.
When you change your WiFi password or install a new router, your TV may remain disconnected until it joins the new network. Even if your TV reconnects automatically, your phone might still be connected to another network, such as mobile data, a guest network, or a different WiFi band.
Other common reasons include:
Your TV is still trying to connect using the old password.
Your phone is connected to a different WiFi network.
The router assigned a new local IP address to the TV.
The TV remote app has stored outdated connection information.
Network isolation settings prevent devices from seeing each other.

Fortunately, these issues can usually be fixed within a few minutes.
Step 1: Make Sure Your TV Is Connected to the New WiFi
Your TV must be connected to the new wireless network before any remote app can detect it.
Open your TV's network settings and verify that it is connected to your current WiFi. If it still shows the previous network or reports a connection error, forget the old network and connect again using the new password.
Once connected, test the internet by opening a streaming app or checking for software updates.
If your TV cannot access the internet, solve that issue first before troubleshooting the remote app.
Step 2: Connect Your Phone to the Same WiFi Network
Your phone must use the exact same WiFi network as your TV.
Many homes have separate 2.4 GHz and 5 GHz networks with different names. Some also have guest networks that isolate connected devices.
Check these points:
Turn off mobile data temporarily.
Connect to your main home WiFi.
Avoid guest WiFi.
Confirm both devices are connected to the same network name.
Even if both devices have internet access, they cannot communicate if they are on different networks.
Step 3: Restart Your TV, Phone, and Router
Restarting your devices refreshes network connections and often restores TV discovery.
Follow this order:
Turn off your TV and unplug it for one minute.
Restart your WiFi router.
Restart your smartphone.
Turn your TV back on.
Open your remote app and search again.
This simple process clears temporary network issues that frequently appear after changing router settings.
Step 4: Refresh the TV Search in Your Remote App
Refreshing the device search allows the app to discover your TV again.
Close the app completely and reopen it instead of leaving it running in the background. Then perform a new device scan.
If your app offers an option to remove previously connected TVs, delete the old connection before scanning again.
This forces the app to look for your TV as a new device instead of trying to connect using outdated information.
Step 5: Check TV Remote Permissions
TV remote apps require permission to access your local network.
On Android, ensure the app has permission to access nearby devices and your local network where required.
On iPhone, make sure Local Network permission is enabled. Without this permission, iOS blocks the app from discovering compatible smart TVs.
Also verify that WiFi access is enabled for the app.
Step 6: Disable VPN or Network Isolation
VPN services and router isolation features can prevent your phone from detecting your TV.
If you use a VPN, disconnect it temporarily and search again.
Some routers include settings such as:
AP Isolation
Client Isolation
Wireless Isolation
Guest Isolation
When enabled, these features stop wireless devices from communicating with each other even though both have internet access.
Disable these settings if you want your phone to control your TV.
Step 7: Update Your TV and Remote App
Outdated software can cause device discovery problems after network changes.
Check for updates on:
Your smart TV
Your remote app
Your phone operating system
Keeping everything updated improves compatibility and fixes known connection issues.
Why Your TV Remote App Is Not Working ? (Fix All Problems)
What If Your TV Still Does Not Appear?
If your TV still does not appear, the problem is usually related to compatibility, network settings, or the TV itself.
Try these additional solutions:
Restart the TV again after reconnecting WiFi.
Remove saved devices inside the app.
Check whether your TV supports network remote control.
Enable remote control settings on the TV if available.
Try connecting with another smartphone.
